Yamaha WR450f - 2 trac?!

[askew]

Has anyone else heard much about this new bike? Apparently Yamaha are doing just a limited run, but it's going to be a 2 wheel drive enduro bike! There's some information on it here:

C'mon, some rich git has to get one just for a laugh.

They are for rich kids at the moment, give it 5 years and half the dirt/enduro bikes sold will be 2 trac!

[Sparks!]

The 2WD yamaha has been out for ages, there was a 450 at a supermoto race back in July in Aug/sept!

Pretty cool I guess.

Wait 'till they make some 2WD superbikes. Unhighsideable and totally steerable with the back-end stepped right out as the front keeps pulling you round the corner. Even faster acceleration off the line due to reduced wheelieage.

Who wil be first to master two wheel drift??

It is a neat system, those hub-centre hydraulic motors must have a lot of potential applications. Beats the hell out of the old 2WD bikes they made in the 70's with a chain running along the front forks .

The mind boggles at the thought of a 2wd superbike! I think riding styles would need to change slightly.

And chain driven down the forks?!?!?! - Danger, Danger!

125cc, 2WD, 8bhp. Ride it anywhere you can think of. Big chain drive to front wheel running along forks.

I've been wondering for a while.

IF you do a stoppy... and keep the throttle on....


can you stoppy for miles??

Unfortunately, I think the power going through the front would tend to just bring the back down.

The problem with 2wd road bikes is matching the speeds of the wheels while leaning over due to the different camber of the tyres. Same reason why traction control doesn't work on a bike.

2wd yamahas have been around for ages, they made a TT600, or whatever they call their 600 single AC bike, years ago.

I think I remember reading that it'll transfer a max of 50% of the power, so it'll take some getting used to...and without the relative safety of the rear brake it'll take some ballcocks to get the hang of it!

Cagiva Geezer - the bike will naturally balance itself. As the rear slips more the front will get more drive.

I can imagine it being a very easy system to get used to, and it'll make riding much safer for sure.
Now they just need to make the rear drive hydraulic too...doing away with chains & sprockets and shaft/belt drives! /
